MEASUREMENT OF ANISOTROPIC ACTIVATION ENERGIES IN HIGH-Tc SUPERCONDUCTORS

doi:10.1088/1004-423X/2/10/006

Abstract

Abstract For single crystalline and melt-textured samples there exist several different activation energies for fluxoid creep, which are related to various vortex orientations and hopping directions. We discuss how to obtain these anisotropic activation energies from magnetic relaxation data and present measured results of a melt-textured YBCO sample.
